Volodymyr B. has been accused of aiding and abetting acts of sabotage carried out on 15–16 November, the National Prosecutor’s Office said on Monday.
He was detained by officers of the Central Bureau of Investigation (CBŚP) on 20 November 2025 as part of the ongoing operation.
Prosecutors claim he assisted the primary suspects by helping to survey locations and prepare further actions.
A court has ordered a three-month remand for the 39-year-old, marking the third person formally charged in the case.
Two other Ukrainians, Oleksandr K., 39, and Yevhenii I., 41, face charges of carrying out terrorist acts for the Russian Federation’s intelligence services against Poland, which carry a potential life sentence.
The acts of sabotage occurred on a key rail route from Warsaw to Lublin – an important line also used for aid missions to Ukraine.
Near Mika, Mazovia, an explosive device destroyed a railway track.
Near Gołąb station in Lublin Voivodeship, a passenger train carrying 475 people had to make an emergency stop due to damaged infrastructure.
According to investigators, evidence shows that in September 2025 Volodymyr B. transported Yevhenii I. to the area of the planned attack along railway line No. 7 near the villages of Mika and Gołąb, enabling him to scout the site, select the location for placing explosives, install a camera device and attach a metal component to the tracks.
Earlier in the investigation, four additional suspects were detained. Three were released, while one was charged with document concealment.
Polish Prime Minister Donald Tusk called the incidents "unprecedented" and noted that Warsaw now regards this as part of a broader campaign of hybrid attacks by Russia targeting infrastructure.
